Low-Cost, Simple to Mod GPS Antenna Splitter!

26 March, 2024 - Reading time: ~1 minute

I have multiple GPS receivers for various projects that all need separate antennas. I came across this "power splitter" that looked like it would do the job - just needs a little modification. Thanks to Mark VK5QI for the idea!

I have upgraded from my Icom IC-7300 to an Icom IC-7610! What were the key differences & features and is the IC-7610 vs IC-7300 a worthwhile upgrade, or just two radios in one?

Australian (VK) Amateur Radio License Numbers

21 March, 2024 - Reading time: 7 minutes

For the past few years I have periodically analyzed and researched the amount of amateur radio licensees in Australia. This is of particular interest to me - to see if we're "going in the right direction" - that being positively increasing amateur radio operators in Australia.ย 

Some have commented to me that "quality over quantity" is better... somehow thinking that there is a "perfect model ham radio operator" out there. Well there isn't - but this article is not focused on that today.

Firstly the recent changes by the ACMA and the Class License means that a new callsign registry was implemented. This meant that obtaining the data is much more difficult than before. ACMA provide a downloadable version of their RRL which is filterable - allowing duplicates and the like to be removed. Since the changes to the callsign registry & class license - it is impossible now to determine who owns what callsign, or in fact, how many callsigns they have - unless you look it up through QRZ.ย  ย 

Nevertheless, we can get some sort of indication of the data and that is presented below.

Key Points:

  • Under the class license, license numbers will continue to increase. Due to the abolishment of annual fees - and with that license renewals - amateur operators are only required to renew their callsign every 5 years. If someone becomes a SK in that time - their callsign could potentially sit there for years until it either:a). expires or b). the estate of the SK remembers to surrender the callsign
  • The numbers below are not "individual operators" as you can have more than one callsign. However they do exclude beacons, repeaters & contest callsigns
  • This data was extracted on 21/03/2024, roughly a month after the class license has commenced.
  • "Unknown" had no license tier assigned to it - presumably a new license that had not yet been processed

Key Takeaways:

  • 15,370 "callsigns" are currently allocated
  • VK2 has the most hams, followed closely by VK3
  • In every state/territory apart from VK8, Foundation exceeds Standard, sometimes almost double.
  • The % increase over 2023 is all positive - but that will be due to 2023's numbers removing duplicate callsigns in the data
  • VK1 has the most hams to general population 1 ham for every 920 people. This is followed very closed by VK7 - 1 ham for every 925 people.ย 
  • The national ham to population is: 1 ham per 1745 peopleย  ย ย 

Compared to some other countries:

  • USA - 1 ham for every 448 people - 757,000 hams (pop. 341 million)
  • Canada - 1 ham for every 555 people (2023) - 73,000 hams (pop. 39 million)
  • UK - 1 ham for every 670 people - 101,000 hams (pop. 68 million)
  • New Zealand - 1 ham for every 782 people - 6,700 hams (pop. 5.25 million)
  • Japan -ย  1 ham for every 326 people - 382,000 hams (pop. 125 million)

As you can see, Australia lags behind quite considerably.

This explains why the Australian ham market is so small - and "lack of activity on the bands".

So how do we improve on this? I believe the ACMA taking on Amateur Radio license services is a step in the right direction. First of all, exams are completely free - you only pay if you pass. No annual fees either. Invite your family, friends, coworkers - anyone you know to take the test and become a ham. There are great benefits to do so. Let's catch up to the rest of the world.
